[0027] Figure 1-2 The material spill prevention device based on photoelectric sensing shown includes a conveyor belt 1; a photoelectric switch 2 is provided on the top of the conveyor belt 1; a blowing device 3 is provided on both sides of the conveyor belt 1; material 4 is provided on the conveyor belt 1; and the photoelectric switch 2 is connected to the blowing device 3.

[0028] Material 4 is transported out of the discharge port via conveyor belt 1. Conveyor belt 1 moves towards photoelectric switch 2. When material 4 is transported to the bottom of photoelectric switch 2, photoelectric switch 2 detects material 4 and controls the blowing device 3 to start. The blowing device 3 blows from both sides of conveyor belt 1 towards the middle, thereby preventing material 4 from spilling off conveyor belt 1, effectively avoiding waste of material 4, pollution of the working environment, and potential safety hazards. At the same time, the fully automatic blowing operation eliminates the need for manual spill prevention and cleaning, reducing the labor intensity of workers and improving work efficiency.

[0029] The conveyor belt 1 includes a roller track 5; a belt 501 is provided on the roller track 5; a mounting bracket 6 is provided on the roller track 5; and a photoelectric switch 2 is provided on the mounting bracket 6.

[0030] The roller conveyor 5 is installed on the ground; the belt 501 is installed on the roller conveyor 5 and can move on the roller conveyor 5 to realize the transportation of material 4; the mounting bracket 6 has a U-shaped structure; the mounting bracket 6 is fixedly connected to the ground; the photoelectric switch 2 is fixedly connected to the mounting bracket 6 and is located above the belt 501 to realize the detection of material 4.

[0031] The roller conveyor 5 includes multiple conveyor rollers 502; the mounting bracket 6 includes a support vertical rod 601; the support vertical rod 601 is located on both sides of the belt 501; the support vertical rod 601 is located between adjacent conveyor rollers 502; the support vertical rod 601 is connected to a support horizontal rod 602; the support horizontal rod 602 is located on the top of the belt 501; the photoelectric switch 2 is located on the support horizontal rod 602.

[0032] A transmission gear is fixedly connected to the end of the conveyor roller 502; the motor of the roller conveyor 5 is connected to a chain, which drives multiple conveyor rollers 502 to rotate; the conveyor roller 502 drives the belt 501 to run by friction between itself and the belt 501, thereby conveying material 4; the support vertical rods 601 of the mounting bracket 6 are symmetrically arranged on both sides of the belt 501 and located between adjacent conveyor rollers 502, playing a stable support role; the support horizontal rod 602, which is fixedly connected to the support vertical rod 601, is arranged horizontally on the top of the belt 501, providing an installation position for the photoelectric switch 2; the photoelectric switch 2 is installed on the support horizontal rod 602. When it is working, the emitter of the photoelectric switch 2 emits infrared light. When the material 4 runs through the belt 501 to the area below the photoelectric switch 2, the light beam is blocked or reflected, and the light signal received by the receiver of the photoelectric switch 2 changes, thereby converting the light signal into an electrical signal. The detection circuit of the photoelectric switch 2 outputs a signal to determine the presence of material 4, thus realizing the detection function of material 4.

[0033] The conveyor belt 1 has a discharge port at one end; the purging device 3 is located on the side of the mounting bracket 6 away from the discharge port.

[0034] The conveyor belt 1 transports the material 4 from the discharge port to the mounting bracket 6; the mounting bracket 6 is located near the discharge port; the blowing device 3 is located near the mounting bracket 6; when the photoelectric switch 2 detects the material 4, the photoelectric switch 2 controls the blowing device 3 to open, so that the blowing device 3 blows the material 4 from both sides of the belt 501 towards the middle.

[0035] The purging device 3 includes a purging nozzle 301; the purging nozzle 301 is located on both sides of the belt 501.

[0036] The blowing nozzles 301 of the blowing device 3 are symmetrically installed on both sides of the belt 501. The airflow is sprayed onto the material 4 through the blowing nozzles 301. The impact force of the airflow is used to blow the material 4 from both sides of the belt 501 towards the center, thereby adjusting the position of the material 4 and preventing the material 4 from shifting and falling.

[0037] The purging device 3 includes a support sleeve 302; an air pipe is provided in the support sleeve 302; one end of the air pipe is connected to the purging nozzle 301, and the other end of the air pipe is connected to the air supply end; a solenoid valve 303 is connected to the air pipe.

[0038] The support sleeve 302 is a hollow round tube, and the air pipe is fixedly connected inside the support sleeve 302. The support sleeve 302 provides physical support for the air pipe, keeping it stable during installation and use, and also protects the air pipe from external damage. The air pipe serves as a channel for gas transmission, with one end connected to the purge nozzle 301 and the other end connected to the air supply end. Compressed air generated at the air supply end is transmitted over long distances and stably through the air pipe. The solenoid valve 303 is connected to the air pipe. The photoelectric switch 2 detects the material 4 and outputs a control signal, energizing the coil of the solenoid valve 303. The valve core of the solenoid valve 303 actuates, opening the air pipe channel, allowing gas to flow quickly from the air supply end through the air pipe to the purge nozzle 301. The photoelectric switch 2 de-energizes the coil of the solenoid valve 303, resetting the valve core and closing the air pipe channel, stopping gas transmission. After receiving the gas, the purge nozzle 301 sprays the gas at a specific angle and intensity, thereby blowing the material 4 on both sides of the belt 501 towards the center.

[0039] The purging device 3 includes a power supply 304; a photoelectric switch 2, the power supply 304 and the solenoid valve 303 are connected in series.

[0040] The power supply 304, photoelectric switch 2, and solenoid valve 303 of the purging device 3 form a closed loop in series. When the conveyor belt 1 transports the material 4 to the detection area of ​​the photoelectric switch 2, the beam emitted by the transmitter inside the photoelectric switch 2 is blocked or reflected by the material. The receiver triggers the circuit to conduct due to the change in the light signal. At this time, the current of the power supply 304 flows through the photoelectric switch 2 to the coil of the solenoid valve 303. The coil is energized and generates electromagnetic force to make the valve core of the solenoid valve 303 move, opening the air pipe channel. The compressed air from the air supply end is sprayed out from the purging nozzle 301 through the air pipe, purging the material 4 from both sides of the belt 501 towards the middle. When the material 4 leaves the detection area, the photoelectric switch 2 returns to its initial state, the circuit is disconnected, the coil of the solenoid valve 303 is de-energized, the valve core resets and closes the air pipe channel, and the purging stops. The entire process is automatically controlled by the on and off of the photoelectric switch 2 to ensure that the purging operation is only performed when the material 4 is detected, which is both energy-saving and efficient.

[0041] The specific workflow of this utility model is as follows:

[0042] When conveyor belt 1 transports material 4 to the detection area of ​​photoelectric switch 2, the beam emitted by the transmitter inside photoelectric switch 2 is blocked or reflected by material 4. The receiver triggers the circuit to conduct due to the change in light signal. At this time, the current of power supply 304 can flow through photoelectric switch 2 to the coil of solenoid valve 303. The coil is energized to generate electromagnetic force, which causes the valve core of solenoid valve 303 to move, opening the air pipe channel. Compressed air from the air supply end is sprayed out from the purging nozzle 301 through the air pipe, purging material 4 from both sides of belt 501 towards the middle. When material 4 leaves the detection area, photoelectric switch 2 returns to its initial state, the circuit is disconnected, the coil of solenoid valve 303 is de-energized, the valve core resets and closes the air pipe channel, and the purging stops. The entire process is achieved by the on and off of photoelectric switch 2 to realize the automatic control of solenoid valve 303, ensuring that the purging operation is only performed when material 4 is detected.
